ADJUSTABLE KNOB 'FOR PLANES;

"Patented Aug. 10,1915.

Appl cat o sfi c eus 19 ws ria rlw 82.1

the borough of 'West Haven and; county of New, Haven, State of Connecticut, have in- -vented,cer,tain new ,and a seful Improvements in Adjustable Knobs for Planes, of which the following is afuflhclear, and eX- act description.

This invention relatesto an im rovedcon- .struction of adjustablegrip mem er or knob for planes or other devices where it is desired to set a knob or like memberimany ,of a number of. different inclinedapositions.

One of the objects of the invention. is the provision of a grip member .for planes, which is universally adjustable i. emwhich can be tilted both-transversely and longitudinally of the plane stock, and clamped in the position in which itwill serve the operators purpose most conveniently. A tilting knob such as contemplated by my invention, can be used to'particular advantage on smoothing planes, as it will enab e the operator to grasp them-plane in a manner conducive to the mostcaccurate work.

Another object of the invention is to provide improved means for clamping the knob in its various adjustments. larly, it is aimed to provide a construction in which the knob may be released by turn-' ing it in one direction after which it may be swung into another position and'clamped 1n that position by turning it in a direction op- I posite to that first mentioned.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a smoothing plane hav ing a knob embodying my invention, Fig. 2 is an enlarged front elevation of Fig. lwith certain parts omitted, Fig.3 is a section on line 33 of Fig. 2, Fig. 4 is a top plan view of the forward end of the stock with the knob proper removed, Fig. 5 is a bottom view of the knob base, detached, Fig. 6 is a bottom plan view of the knob proper, and Fig. 7 is a detail view of the clamping bolt and nut.

Referring to the drawing, I have shown an adjustable knob 10 as applied to a smoothing plane having a stock 11, bit or cutter 12 and handle 13. The knob proper More pa-rticu is of more ,Q1";1SS- usual outer configuration e qen atltll bo to mhi is m o ,as shown at 10 In Fig 6, in order to fitthe convex. upper surface 14 of a knob base 15 von the bedor sole 16 ofthestock. The base l5 is ,detachably applied to the upper surfaceaOfthe bed .or sole ,16 ofthe stock by means such as fastening screws 15 The base, which is formed as a ,portion of a- Sphe h a diame r so ewhat grea than that of thelower portion of the knob (which rests on it, and at the center of the -;base thesaineis provided with a cruciform slot 17. A clarnping bolt'18has ahead 19 located in the space beneath the base 15 and ashank 20 passing upward out of the slot 17 and through the knob. The, head 19 of ibolt 18 ,is .:too large to pass through the slot 17, and assemblage is effected by extending the shank of the screw upward through the ;;base before thelatter is secured to the stock byrthescrews 15 The upper portion ofthe knob is .counterbored to receive .a cylindrical nut 21 having interior screw threads engaging the, threads 18 .01 the end of theshank' The under surface of the base 15 is provided with a plurality of concentric ribs 22, and the upper surface of the screw head 19 is provided with a plurality of teeth 23 adapted to engage these ribs and also to engage the corners of the slot 17 whereby the knob may be tightly clamped in different adjustments when the nut 21 is screwed up sufliciently on the bolt 18.

It will be understood, that when the knob has itsaXis directed perpendicularly to the plane of the bed 16, the teeth 23 of the head 19 will interlock with the corners 17 of the slot 17 when the nut 21 is screwed up tightly on the bolt 20. To release the knob from this position, it is usually merely necessary to turn it in. an anti-clockwise direction which will release the nut 21 by the frictional fit between said nut and its socket in the knob. Upon release of the clamping bolt the knob may then be shifted into any of a large number of inclined positions with the shank 20 of the bolt passing through the middle of the slot or through any one of the four corners thereof, and with the head 19 of the bolt engaged with the corners 17 of the slot or with the ribs 22. WVhen the knob has been moved to the desired angular position, it may be tightened versely of the plane are represented.

In case an especially tight clamping of I the knob is desired, the nut 21 may be screwed up by a screw-driver fitting a nick 21 in said nut, and this screw-driver nick is also useful where difficulty is encountered in releasing the knob by hand inthe manner described.

I do not limit myself in all aspects of the invention to a knob located in front of the cutter of the plane, and in some aspects of the invention it is not essential that a tilting knob located in front of the cutter be adjustable both transversely and longitudinally of the plane stock. 7

Without limiting myself to the construction shown, I claim:

1. The combination with a plane, of a universally adjustable grip member therefor; substantially as described.

2. The combination with a plane, of a tiltable knob therefor and means to clamp and release the knob by a turning movement thereof; substantially as described.

3. The combination with a plane stock, of a knob applied to said stock and tiltable Copies of this patent may be obtained for transversely of the stock and longitudinally thereof; substantially as described.

a. The combination with a plane, of adetachable knob, and means for clamping the knob to the plane in any of a number of positions wherein the knob is tilted either transversely 0r longitudinally of the plane;

substantially as described.

5. In a plane, a universally adjustable tilting knob, and means to clamp and release the knob; substantially as described.

6. In a plane, the combination of a stock, a cutter in the stock, a handle at the rear of the cutter, a tilta-ble knob in front of the cutter, and means to clamp and release the knob by a turning movement thereof; substantially asdescribed. 1

7. The combination with a plane stock, of a concavo-convex member detachably secured to the bed of said stock and having a, slot therein, a knob resting on the upper convex surface of said member, a clamping device having a head confined between the bed of the stock and the under concave surface of said member, and provided with a shank passingupward through said slot into said knob, and a nut threaded on said shank to clamp the knob in position; substantially as described.

In witness whereof, I have hereunto set my hand on the 30th day of July 1913.
